The DI-21 determines the tensile strength, stretch and TEA (tensile energy absorption) of paper and board for Q.C. (quality control) and R&D (research and development). This equipment is absolutely user friendly and reliable due to its built-in exclusive testing software and its rugged and accurate mechanical construtction. It offers complete statistics, a parallel port for the connection of a local printer and a RS232 serial port for the connection to a host computer for data transfer. Major Technical Characteristics Measuring range 0 - 500 N Resolution 0,01 N Selectable testing units N and kgf Testing speed (programable) 1 - 200 mm/min Return speed 300 mm/min Pneumatic clamps 25 mm width Clamping length (programable) 100 - 180 mm Clamping pressure (adjustable) 0 - 6 bar Rupture level 20 - 100% Pneumatic clamps with built-in sample detection ensure an easy, safe and comfortable operation, preventing the slipage of the sample during tests and minimizing the risk of human errors. Clamps design prevent operator from touching the sample in the testing area. The DI-21’s attractive modern design houses a lightweight and sturdy aluminium frame, accurate Star linear bearings and ball screw,precision HBM load cell, heavy duty step motor, alphanumeric backlighted display and dial for the indication of the clamping pressure. The DI-21 can be delivered under request with 50 mm width clamps and 100 N capacity, a special version suitable for low resistance papers like tissue. Optional accesories: Delamination device model DI-DEL (Z bond test) · Precision Sample Cutter model 2G-15 (15 x 300, 25 x 300 or 50 x 300 mm) Applicable standards: ISO 1924-2 · ISO 3781 · TAPPI T-494 · NM-ISO 1924-2 · NM-ISO 3781
